순간 고도 변화에 대한 위성 영상 기기의 Time Delay and Integration 일치 연구 = Study on the Synchronization of Time Delay and Integration against Osculating Altitude Variation in Satellite Image

다국어 초록 (Multilingual Abstract)

The synchronization of Time Delay and Integration (TDI) against the temporal variation of osculating altitude in the operation of high resolution satellite imager was studied. The characteristics of osculating altitude variation was analyzed and its impact on the performance of TDI imger was also investigated. A practical line rate control method was proposed to compensate instantaneous TDI mismatch due to the osculating altitude variation, so that geometrical performance enhancement was achieved by the proposed method. This study is applicable to real satellite operation and can be useful for satellite image quality enhancement.
